IPC: A01J11/04
Filed: 1932-07-25
Abstract: 404,729. Deodorizing milk or cream. DUNLOP, S., 49, Chancery Lane, London.- (Murray, H. L. ; 15, King Edward Avenue, Epsom, Auckland, New Zealand.) July 25, 1932, No. 20923. [Class 49.] Milk or cream is deodorized by heating it, injecting steam, preferably dry saturated steam, into a stream of the heated liquid and introducing the mixture into an evacuated container in such manner and at such a velocity that the stream is directed along a circular path to centripetally vapour from the liquid, and separately withdrawing the vapour and the liquid. The preliminary heating of the liquid may consist of a flash pasteurization at about 200‹ F. for cream and 165‹ F. for milk. The treatment chamber 1, which is preferably made of stainless steel, has a removable cover 2, with a rubber &c. joint 3, carrying the outlet 21 connecting the chamber to the vacuum means, a water-operated ejector condenser 11. The lower portion of the chamber 1 is enclosed in a jacket 5 through which the waste water from the condenser 11 passes for cooling, leaving by outlet 13. The water is fed from the condenser 11 to the jacket 5 through an extension 10, an aperture 37 in the wall of the jacket allowing the vapours withdrawn from the chamber 1 to pass direct to the outlet 13. The liquid to be treated is mixed with steam and supplied tangentially to the chamber 1 through a pipe 31 with a fish-tail aperture 32. The liquid is fed to pipe 31 through a pipe 28 from a float tank 27 which may be constructed as set forth in Specifications 220,627 and 270,509, [both in Class 49, Food &c.]. The tank 27 is supplied from the pasteurizer. A nozzle 33 supplied with steam through a stop valve and a reducing valve is disposed in pipe 31 adjacent to the liquid supply pipe 28. The mixed steam and liquid pass at high velocity through the pipe 31 into the chamber, on entering which the liquid is atomised and is washed by the steam. The liquid passes centrifugally down along the walls of the chamber, and the vapours and odours are drawn upwards through pipe 22. The liquid is collected by means of the cooling jacket 5, and an anti-swirl baffle 15 which directs it to a suction pipe 23 through which it is delivered by a centrifugal pump 24 and a check valve 26 to the exit pipe 25. Specification 314,022, [Class 49, Food &c.], also is referred to.

Title: Process for the manufacture of minute capsules and capsules obtained by such process
IPC: A61K9/50
Filed: 1963-05-28
Abstract: Minute capsules each having a solid or liquid nucleus enclosed by a seamless, rigid wall of hydrophobic, film-forming, polymeric material are prepared by establishing a system comprising a liquid vehicle constituting over 70% of the system and comprising a solvent for the polymeric material and a phase-separation-inducing solute and dispersed therein, particles of the nucleus material and the polymeric wall-forming material, the solvent being chosen so that the polymer is soluble therein at elevated temperatures and insoluble at a lower temperature.  The system is heated with agitation to a temperature at which the polymer dissolves, whereupon, the phase-separation-inducing solute causes a separate liquid phase of polymer and solvent to be formed which has a viscosity between 100 and 10,000 centipoises and which deposits on the core material particles.  Thereafter, the system is cooled with continued agitation to a temperature at which the liquid capsule walls give up the solvent to give the finished capsules which may be separated, washed and dried. Examples relate to the encapsulation of aspirin in ethyl cellulolose using cyclohexane as solvent and butyl rubber as phase-separation-inducing solute (optionally, acetic anhydride may be present to clear potentially toxic materials, e.g. salicylic and acetic acids, from the aspirin) and the same system using an aromatic-type petroleum solvent; reference is also made to the encapsulation of ammonium dichromate, acetyl p-amino phenol, amphetamine sulphate, aluminium aspirin, sodium bicarbonate, gelatin, cellulose acetate hydrogen phthalate, polyvinyl pyrrolidone, mannitol, glyceryl guiacolate, dextro-methorphan hydrobromide, calcium gluconate and carboxymethyl cellulose. Other coating polymers mentioned are ethyl hydroxy ethyl cellulose, polyvinyl pyrrolidone/vinyl acetate and vinyl chloride/vinyl acetate copolymers, other solvents are n-hexane plasticized with monoacetylated glyceride, ligroin, methyl cyclohexane, toluene/cyclohexane, benzene and toluene. Polybutadiene is mentioned as an alternative phase-separation-inducing solute.ALSO:Microcapsules each having a solid or liquid nucleus enclosed by a seamless, rigid wall of hydrophobic, film-forming, polymeric material may contain as nucleus material a medicament, those specified being acetyl-p-aminophenol, amphetamine sulphate, aluminium aspirin, sodium bicarbonate, glyceyl guiacolate, calcium gluconate and dextromethorphan hydrobromide.  Specified film-forming materials are ethyl cellulose, ethyl hydroxyethyl cellulose, polyvinyl pyrrolidone/vinyl acetate and vinyl chloride/vinyl acetate copolymers.

Abstract: 382,328. Loom warp stop-motions. SPITZ, E., Policka n Svitavy, Czecho- Slovakia. July 28, 1931, No. 21483. [Class 142 (i).] The reciprocating bars of a warp stopmotion, employing notched bars and drop wires, are operated from a shaft 24 which is rocked, through clutch mechanism comprising a fixed member 23 and a slidable member 25, by means of an eccentric on the tappet shaft, the clutch members being automatically disconnected when a reciprocating bar is held against movement. Endwise displacement of the member 25, as a result of thread breakage, rocks an arm 28 and its associated shaft 29 to bring a bunter into the path of the lay and effect stoppage of the loom. Alternatively the rock shaft 24 may be so connected with the bunter that the latter is left in the path of the lay when the shaft is held against movement by a fallen drop wire. The reciprocating bars 13 are mounted within fixed notched bars 12 provided with a groove on the underside to engage a bar 16 on endplates 11 and are held in position by means of a detachable coverplate 17. The notches of the bars 12, 13 are cut at an angle to the face so as to turn a fallen drop wire into an angular position and push the warp threads on either side clear of the broken thread.
